The elliptical, 10 x 20 km wide Laguna Caldera SE of Manila forms the middle lake-filled basin of the three-pronged, dinosaur-footprint-shaped Laguna de Bay, the largest lake on Luzon Island. Pre-caldera Pleistocene volcanism formed basaltic to basaltic-andesitic volcanoes, including Talim Island and Mount Sembrano stratovolcanoes on opposite sides of the current caldera. The caldera, whose lake surface is only 1 m above sea level, may have formed during at least two major explosive eruptions about 1 million and 27,000-29,000 years ago. Post-caldera volcanism formed maars of young, but unknown age at the southern end of elongated Talim Island, which forms the SW rim of the caldera. Jalajala is a solfataric field on the flank of Mount Sembrano on the Jalajala Peninsula, which forms the eastern rim of the caldera.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The center of the three-pronged, dinosaur-footprint-shaped Laguna de Bay in the center of the NASA Space Shuttle image (with north to the upper right) is Laguna Caldera. The caldera, whose lake surface is only 1 m above sea level, may have formed during at least two major explosive eruptions about 1 million and 27,000-29,000 years ago. The city of Manila lies along Manila Bay at the top center, and the large caldera at the lower left is Taal. At the extreme right is the Pacific Ocean.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).
